FIELD

The invention relates to a seat arrangement for a means of transport, in particular for a means of passenger transport, in which the seat arrangement is arranged on the means of transport by means of a fastening device.

BACKGROUND

Such means of transport are provided and suitable for being able to transport a plurality of people and are, for example, rail vehicles or airplanes. Corresponding rail vehicles are, for example, local and/or long-distance trains, suburban trains, subways and the like. There is a need to optimise the use of the available space in such means of transport as much as possible. As many travellers as possible should be able to be accommodated in one means of transport. By providing conventional seat arrangements in which the user takes a seat in the conventional sitting posture with bent legs, a user takes up a comparatively large amount of space in the means of transport. In comparison, by providing standing locations, a considerably larger number of people can fit into the means of transport. However, a standing location also often implies an unacceptable loss of travel comfort, especially on longer journeys. Another disadvantage of the previous seat arrangements is that they cannot be modified with regard to the needs of the users. For example, the orientation of the seats cannot be changed. An adjustment of the orientation, for example to the direction of travel of the means of transport, is generally not possible. Likewise, seating groups are usually provided, in which two pairs of seats face one another, or in which the pairs of seats are arranged in a row one behind the other. Accordingly, an adjustment to the needs of small travel groups or families is not possible using such seating groups.

SUMMARY

The object of the present invention is to provide a seat arrangement which overcomes the disadvantages mentioned in the introduction. Furthermore, it is the object of the invention to provide an interior of a means of transport which overcomes the disadvantages mentioned in the introduction.

One substantial aspect of the invention is to provide a seat arrangement for a means of transport, in particular for a means of passenger transport, in which the seat arrangement can be arranged on or in the means of transport by means of a fastening device. The seat arrangement is intended and suitable for providing a sitting position at standing height, with the seat arrangement comprising at least one frame element, with a seat cover being arranged on or into the at least one frame element and the seat cover being a knitted fabric.

The at least one frame element preferably includes an inner surface. The seat cover is therefore advantageously arranged, at least in portions, on this inner surface. Alternatively, it is preferred if the seat cover is arranged on or above the inner surface, at least in portions. It would also be conceivable that the seat cover encloses the inner surface, at least in portions. The seat cover is advantageously provided and determined to withstand the force introduced by the user. Accordingly, the seat cover advantageously has a corresponding stability. Accordingly, no further supporting elements are advantageously arranged on the inner surface. According to the invention, the seat cover is a knitted seat cover or a knitted fabric. Such a knitted fabric is advantageously made with a knitting machine. This advantageous use of a knitted fabric allows a high degree of variability in the design of the regions with different elasticities. Such knitted fabrics can advantageously have both flexible and rigid or fixed portions. Compared to conventional woven fabrics, knitted fabrics can be produced very easily and inexpensively.

According to a preferred embodiment, the seat cover is a flat knitted fabric. A flat knitted fabric is a substantially flat structure that is surrounded by outer edges. This flat structure can have any shape, for example polygonal, in particular square, round, elliptical, etc. If the thickness of the flat knitted fabric is not considered, a substantially two-dimensional flat structure can be assumed. According to a further embodiment, the seat cover is a tubular knitted fabric or a tubular knitted fabric. Such tubular knitted fabrics can be viewed as flat structures lying opposite each other, which are connected to one another at two outer edges. The knitted fabric is advantageously produced using a 3D knitting method. Such an advantageous technique allows both flexible and rigid regions to be incorporated within a knitted part. Such a knitting method can preferably be used in addition to different strains, different comfort zones, patterns, and colours in an extremely simple manner. The method allows a large number of knitted covers to be produced in one pass without being removed. Such a knitted seat cover can be ergonomically and individually adapted to the body. Manufacturing can be carried out as simply as possible, since only those materials have to be processed which are necessary for the seat cover. Additional upholstery elements are no longer necessary. According to a further preferred embodiment, the seat cover or the knitted fabric consists of materials which are selected from among: polyester, polypropylene, polyamide, Tencel, or wool. The seat cover advantageously consists only of one of these materials or also a combination of these materials. Of course, other materials are also suitable which are suitable for a knitting process alone or in combination with other materials. The seat cover, or rather the knitted fabric, advantageously has integrated reinforcing fibres. Such integrated reinforcing fibres which are knitted in can absorb the highest mechanical tensile forces, preferably without undulation. It is advantageous in this context that the reinforcing fibres extend biaxially in the seat cover or the knitted fabric. The advantageous flat structure thus has reinforcing fibres extending along the two directional axes. In the case of a tubular knitted fabric, the reinforcing fibres would thus extend along a tangential and along an axial direction. The reinforcement threads are preferably wrapped in the 0 and 90° directions by mesh threads in such a way that no damage to the reinforcement fibres occur. The reinforcing threads are preferably made of glass, carbon, basalt, or aramid. The mesh threads are preferably made of polyester, polypropylene, polyamide, Tencel, or wool.

In the following, a coordinate system with a height axis (X), a width axis (Y), and a depth axis (X) is used for the seat arrangement. A coordinate system with a height axis (XI a width axis (C), and a depth axis (X′) is used for the at least one frame element. The respective axes can also have two directions.

The frame element preferably comprises an upper region for supporting the back and at least one seat region integrated in the at least one frame element. The at least one frame element accordingly takes on the function of a backrest and, likewise, the function of a seat part. Accordingly, an extremely simple and inexpensive seat arrangement is provided. The first and the second seat regions of the at least one frame element preferably have an extension along a depth axis (X′) which is between 10 cm and 50 cm, more preferably between 15 cm and 40 cm. Due to the configuration with a seat region integrated in the at least one frame element, the seat arrangement thus already has a smaller extent in a depth direction of the seat arrangement or of the means of transport than the conventional seat arrangements. Since the at least one frame element already comprises an integrated seat region, no additional seat part is necessary or provided. Furthermore, the seat region is arranged at a height that allows sitting or leaning at standing height. Such seat arrangements are also referred to as a sit-stand seat. Due to the advantageous configuration as a sit-stand seat, the occupant of the seat arrangement does not assume a conventional sitting posture. Rather, the occupant assumes a sitting posture in the seat arrangement which approximately corresponds to a standing posture. This sitting posture requires less space than the conventional sitting posture, in which the legs are angled at approximately a right angle. The advantageous seat arrangement thus has a substantially smaller depth than a conventional seat. The passengers of the means of transport are therefore offered an extremely simple, yet comfortable, option for sit-standing. In contrast to standing, the pressure on the legs and blood circulation is reduced when sit-standing. This promotes healthy “dynamic sitting”. Accordingly, seating options are offered to as many travellers as possible, whereby they also provide the travellers with an acceptable level of travel comfort. Furthermore, the space available in the means of transport is optimised as much as possible. The seating region is advantageously arranged at a height between 40 cm and 150 cm, more preferably at a height between 40 cm and 130 cm. The seat height can advantageously be matched to the intended target persons. A seat arrangement which is intended for children or the elderly would preferably have a seat height in a range between 40 cm and 60 cm. A seat arrangement for adults would rather have a height in a range between 80 cm and 150 cm, more preferably in a range between 80 cm and 130 cm.

According to a preferred embodiment, the at least one frame element is formed by a lower portion and an upper portion. The at least one frame element preferably has a base area which extends along a height axis (Z) and along a width axis (r). This base area is preferably designed as a polygon. The base area is preferably designed as a square. The base area is preferably substantially designed as a rectangle or is substantially designed as a trapezoid. The term “substantially” used should be construed as including minor tolerance deviations in terms of a shape of a length or an angle. Thus, the deviation may be an angle of preferably less than 10°, more preferably less than 7.5°, even more preferably less than 5°. This also applies to the term “substantially” used hereinafter. According to a further preferred embodiment, the lower portion and the upper portion of the at least one frame element form the at least one frame element integrally, in one piece or in multiple pieces, in particular in two pieces. In the case of a one-piece design, the frame element, or rather the upper and the lower portion, is produced as a single and unitary part, or as a so-called monoblock. The respective portions are advantageously made of the same material. A one-piece design is understood herein to mean that, although not all portions are made from a single and unitary part, they are not only firmly connected, but are so closely connected to one another that they do not appear as a plurality of joined components and in any case can no longer be separated from one another without being destroyed.

Advantageously, the lower portion comprises at least one first transverse portion extending substantially along a width axis (Y′) and one second transverse portion extending substantially along a width axis (Y′). The upper portion preferably comprises a third transverse portion extending along the width axis (Y′). The first transverse portion and the second transverse portion preferably have an extension along a depth axis (X′). This extension is advantageously increased in comparison to an extension of the third transverse portion along the depth axis. Preferably, the first and/or the second transverse portion form, at least in portions, the seat region. Preferably, the first and second transverse portions extend in opposite directions along the depth axis. The first and the second transverse portion are preferably connected to one another. The first and the second transverse portion are preferably formed integrally or in one piece. The first and the second transverse portions are advantageously spaced apart from the third transverse portion along the height axis (Z′) and are connected by means of two strut elements. The first transverse portion and the second transverse portion preferably have a greater extent along a depth axis (X′) than the third transverse portion. It is advantageous that the lower portion and the upper portion enclose an inner surface. Likewise, the first and the second transverse portions enclose the two strut elements, and the third transverse portion encloses the inner surface. The at least one frame element is thus substantially plate-like, in which case, at the lower end along the height axis, the first and second transverse portions having an enlarged depth extension are provided, as a result of which the seat region is formed at least in portions.

According to a further advantageous embodiment, the seat cover designed as a tubular knitted fabric has two opening sides. A first opening side is preferably closed. This can be done, for example, by sewing. The seat cover designed as a tubular knitted fabric is advantageously arranged over the at least one frame element. The seat cover is preferably arranged on both sides over an inner surface of the at least one frame element enclosed by the frame element. A first opening side of the seat cover is advantageously arranged along the height axis (Z′) above the second opening side. The closed first opening side preferably abuts the upper portion or the third transverse portion of the at least one frame element. When using the advantageous tubular seat cover, the at least one frame element can be designed in one piece or integrally. The tubular seat cover is therefore preferably guided over the at least one frame element. An integral configuration of the at least one frame element has the advantage that the at least one frame element has increased stability and rigidity. Furthermore, no additional connection options need to be provided, such as bores, plug connections, screws, etc. After the tubular knitted fabric has been pulled over the at least one frame element, the second opening side can also be closed. This could be a re-openable closure, for example a zipper, push buttons, or the like. This makes it possible to replace or clean the seat cover if necessary.

According to a further advantageous embodiment, the seat cover is arranged or fastened on at least two inner sides of the at least one frame element. Such a seat cover can preferably be a flat knitted fabric. The seat cover configured as a flat knitted fabric is preferably equipped with at least two piping lugs. These piping lugs are preferably each arranged or clamped in a piping rail of the at least one frame element. This piping rail is advantageously arranged on an inner side of the at least one frame element, as a result of which this piping rail thus faces the inner surface of the at least one frame element.

In the advantageous multi-piece embodiment of the at least one frame element, the at least one frame element consists of a plurality of parts which are preferably releasably connected to one another. The at least one frame element is advantageously configured in two parts and consists of the upper portion and the lower portion. It is advantageous that the two portions be U-shaped. For this purpose, the strut elements are advantageously interrupted and equipped with a detachable connection. Such a releasable connection is, for example, a plug connection. Two portions of the strut element are preferably inserted one into the other. Security devices, such as pins, screws, bolts, etc., are also advantageously provided, by means of which the plug connection can be secured against unintentional loosening. Such an embodiment is particularly advantageous if a seat cover is to be arranged on an inner side of the at least one frame element pointing towards the inner surface. For this purpose, as already described, a piping rail can be arranged on the inside of the at least one frame element. A piping lug of the seat cover can then be introduced into such a piping rail. Said introduction can take place particularly easily if the at least one frame element can be separated or is configured in multiple pieces. The piping rail can be provided at least on the strut elements extending along the height axis (Z′). Alternatively or cumulatively, a piping rail in which a corresponding piping lug of the seat cover is arranged can also be provided on the third transverse portion and/or on the first or second transverse portion.

According to the invention, the at least one frame element can be pivoted relative to the fastening device about a pivot axis extending along a width axis (Y′, Y). The at least one frame element can therefore be pivoted as a whole with respect to a pivot axis. As a result, both the advantageous upper region for supporting the back and the advantageous integrated seat region are simultaneously pivoted or rotated about the pivot axis. In contrast, only the backrest can be pivoted about a pivot axis in conventional seat arrangements. According to a further preferred embodiment, the at least one frame element can be pivoted in at least two pivoting positions. The at least one frame element is preferably pivotable in three pivoting positions. The at least one frame element is preferably pivotable into a first pivoting position. In the first pivoting position, the frame element preferably extends substantially perpendicular to an imaginary plane which extends parallel to the floor of the means of transport. The at least one frame element is advantageously pivotable into a second pivoting position, which is inclined relative to the first pivoting position by an angle of inclination (α). The at least one frame element is preferably pivotable into a third pivoting position, which is inclined relative to the first pivoting position by an angle of inclination (β). Advantageously, a second imaginary plane can be defined, which runs perpendicular to the first imaginary plane. The at least one frame element in the first pivoting position is advantageously arranged substantially in the second imaginary plane. In the second and the third pivoting position, the at least one frame element preferably includes an angle of inclination α or β with the second imaginary plane. It is advantageous in this context that the at least one frame element be inclined in directions opposite the second and the third pivoting positions along a depth axis (X). The angle of inclination (α) and the angle of inclination (β) thus advantageously have different signs (±). However, the angle of inclination (α) and the angle of inclination (β) preferably have the same amount. The angles of inclination (α, β) are preferably in a range between 10° and 80°, more preferably in a range between 20° and 70°, in which case the at least one frame element and the second imaginary plane include the angles of inclination (α, β).

According to a further preferred embodiment, a latching apparatus is provided, by means of which the at least one frame element can be locked in at least one pivoting position. The at least one frame element can preferably be locked in at least two or at least three pivoting positions by means of the latching apparatus. Advantageously, the at least one frame element can be locked in all intended pivoting positions by means of the latching apparatus. If the at least one frame element is pivoted into the first pivoting position and locked in this pivoting position, it is aligned advantageously upright and substantially arranged in the second imaginary plane, which runs perpendicular to the first imaginary plane. In this position, the seat arrangement is not occupied by a user. The effective depth of the seat arrangement in this position substantially corresponds to the sum of the depth extensions of the first and second transverse portions of the at least one frame element. The seat arrangement accordingly takes up a minimal space in the first pivoting position along the depth axis. The fact that the at least one frame element takes up very little space when the upright extension is extended makes possible, for example, effective mounting of the seat arrangement. Furthermore, in the case of a plurality of seat arrangements arranged in a row, the intermediate space can be enlarged by pivoting into the first pivoting position.

According to a further advantageous embodiment, in the second pivoting position of the at least one frame element, a first seat region is formed at least by the first transverse portion. In the third pivoting position of the at least one frame element, a second seat region is preferably formed at least by the second transverse portion. The at least one frame element can advantageously be pivoted into the first pivoting position, into the second pivoting position and into the third pivoting position and can advantageously be latched in these pivoting positions. Due to the preferred extension of the first transverse portion and the second transverse portion in directions opposite along the depth axis (X) and due to the opposite angles of inclination (α, β) of the at least one frame element in the second and the third pivoting positions, the first and the second seat regions are in along directions opposite to the depth axis (X). Such a configuration allows the seat alignment to be adapted extremely easily to the direction of travel. Wth some means of transport, such as rail vehicles, a change of direction can take place during travel. This can be done, for example, when entering or leaving a terminal station. However, some users are uncomfortable when travelling backwards. The orientation of the seat arrangement can be adapted in a simple manner to the direction of travel by simply pivoting, for example, from the second to the third pivoting position. According to a further preferred embodiment, the at least one frame element can advantageously be pivoted into the first pivoting position and the second pivoting position and can advantageously be locked in these pivoting positions. An embodiment would also be conceivable in which the at least one frame element can be pivoted into the first pivoting position and into the third pivoting position and can advantageously be locked in these pivoting positions. According to these embodiments, the seat arrangement would therefore continue to be configured for an upright pivoting position for only one seat direction. According to a further preferred embodiment, the at least one frame element can advantageously be pivoted into the second pivoting position and into the third pivoting position and can advantageously be locked in these pivoting positions. According to this embodiment, the seat arrangements would be designed for two opposite seating directions. However, an upright pivoting position for mounting would not be provided. Finally, it would be conceivable that the at least one frame element can only assume the second pivoting position or the third pivoting position and be locked or fixed in this pivoting position. Of course, it would also be conceivable that the at least one frame element can be pivoted into further pivoting positions and can be locked in these pivoting positions. Such further pivoting positions could lie between the first pivoting position and the second pivoting position or between the first pivoting position and the third pivoting position. The corresponding angles of inclination would then be smaller than the angles of inclination (α, β). This would allow the occupant to adjust the inclination of the upper portion to support the back according to their needs. According to a further advantageous embodiment, in the second pivoting position of the at least one frame element, the first seat region extends substantially parallel to the first imaginary plane, or horizontally. In the third pivoting position of the at least one frame element, the second seat region preferably extends substantially parallel to the first imaginary plane, or horizontally. The first transverse portion preferably comprises an upper surface which, in the second pivoting position, extends substantially parallel to the first imaginary plane. The second transverse portion advantageously comprises an upper surface which, in the third pivoting position, extends substantially parallel to the first imaginary plane.

The seat cover advantageously has at least two regions which have different elasticities. A first region advantageously has a lower elasticity than the second region. The second region is advantageously elastically deformable by the action of a force. The first region is preferably arranged along the height axis (Z′) above the second region. The first region of the seat cover is preferably arranged in the upper region for supporting the back of the at least one frame element or the inner surface. Accordingly, the second region is arranged in a central and/or lower region of the at least one frame element or the inner surface along the height axis (Z′). However, an embodiment would also be conceivable in which the second region having a higher elasticity is arranged in a lateral region of the inner surface. Of course, it is also conceivable that a plurality of regions having different elasticities are provided in the seat cover, which are suitable and are intended to ensure an ergonomic adjustment of the seat cover to the user or the user's back. The first upper region advantageously has a lower elasticity and is therefore more rigid or stronger. This region advantageously serves to support the shoulder region of the user. The seat cover is preferably connected to the at least one frame element or firmly connected to it from the bottom upwards. This connection can be implemented in a variety of ways, for example by means of a piping lug guided in a piping rail or by enclosing the frame element with the tubular knitted fabric. The seat cover is preferably deformable in the second region, which is arranged in a central lower region of the inner surface, by a corresponding action of force or loading. Such a load arises, for example, when the occupant leans against the seat cover. Such a deformation can advantageously be described as a three-dimensional deformation, or as a bulge. The advantageous second region of the seat cover is therefore suitable and provided for supporting the lower back and the gluteal region of the occupant. Due to the increased elasticity, the seat cover can be stretched in its second lower region under load, which results in a corresponding bulge of the seat cover. Such a bulge can advantageously also be assigned to an effective seat surface and also serve for supporting the gluteal region and the lower back of the user. The seat cover is advantageously designed in such a way that the bulge formed in the second region is correspondingly adapted when pivoting from the second to the third pivoting position and thus extends in the opposite direction.

According to a further preferred embodiment, the seat cover has a third region which is provided and suitable for providing cushioning for the at least one seat region. The third region is preferably arranged on the first transverse portion and/or on the second transverse portion. The third region is advantageously arranged along the height axis (Z′) below the second region. This third region is preferably connected to the at least one frame element. This third region is preferably connected to the first and/or second transverse portion of the at least one frame element. It is advantageous that this connection be a detachable connection. Such a connection could be, for example, a clamp connection, a plug connection, or a connection by means of a hook. It would also be conceivable that an additional element is provided to enlarge the effective seat surface, which also serves to connect the third region of the seat cover to the at least one frame element. For example, the third region of the seat cover could be clamped between the at least one frame element and the additional element. According to a further concept of the invention, the third region of the seat cover can serve as padding for the first and/or second seat region. For this purpose, more material of the seat cover may have been introduced into the third region, so that the third region has an increased thickness. Alternatively or cumulatively, the third region could be lined with an additional material that has good cushioning properties. Such a material could also have been applied to the outside of the third region. The third region of the seat cover is thus advantageously arranged on the first and/or the second seat region of the at least one frame element and, optionally, on the additional element. According to a further advantageous embodiment, the second region merges into the third region without interruption. Accordingly, the effective seat surface advantageously also includes the transition between the third and the second regions. As already described, the effective seat surface can also comprise a portion of the second region of the seat cover. According to a further advantageous embodiment, a cut-out is provided between the second region and the third regions. The cut-out preferably extends over the substantially entire width of the inner surface. The second and the third regions of the seat cover are therefore preferably only connected via web-like portions which are arranged on the longitudinal portions of the at least one frame element. The second opening side of the preferably configured so as to be a tubular seat cover could preferably also be contained in a third region of the seat cover. It would also be conceivable that the seat cover is not connected to the first transverse portion. The seat cover would therefore not have a third region.

According to a further preferred embodiment, the seat arrangement only comprises a frame element which is arranged on the fastening device. The frame element is advantageously arranged between two receiving devices of the fastening device. Each of the receiving devices is preferably arranged on a fastening element which is suitable and provided for attaching the receiving device to the means of transport. According to a further preferred embodiment, the seat arrangement comprises two frame elements which are arranged on the fastening device. The two frame elements are preferably arranged next to one another along the width axis (Y). The two frame elements can be of the same or different designs. Each of the two frame elements can have features according to the embodiments described in the introduction, independently of one another. The two frame elements can preferably be pivoted independently of one another about a common pivot axis extending along a width axis (Y) relative to the fastening device, preferably pivotable by the angles of inclination (α, β).

According to a preferred embodiment, the at least one frame element is made of a metal alloy, preferably of an aluminium alloy. The fastening device can also be made at least partially of a metal alloy, preferably of an aluminium alloy. This allows the seat arrangement to be built as light-weight as possible.

The underlying object is also solved by an interior device of a means of transport, in particular, a means of passenger transport, which comprises at least one seat arrangement according to any of the preceding embodiments. The interior device can be equipped with all the features already described above in the scope of the seat arrangement, individually or in combination with each other, and vice-versa. The interior device preferably comprises a plurality of seat arrangements. According to a preferred embodiment, the at least one seat arrangement is arranged on the means of transport so as to be stationary or displaceable by means of a guide device, in particular a rail device. The guide device can be arranged on the floor or a wall element of the means of transport. The seat arrangements can thus advantageously be accommodated in a stowage region of the means of transport, for example a rail vehicle. The space of the means of transport could thus be filled with bulky luggage, for example bicycles. Depending on requirements, a specific number of seat arrangements can be transported from the stowage region into the interior and can be defined accordingly at specific points. This can be done by means of corresponding advantageous latching devices.

Finally, a means of transport, in particular a means of passenger transport, for example a rail vehicle, is provided which has at least one interior device or at least one seat arrangement.

The seat height is preferably in a range between 40 cm and 60 cm. FIGS. 2a and 2b show a seat arrangement 1 which is more suitable for adults. The seat height would be in a range between 80 cm and 150 cm, more preferably in a range between 90 cm and 130 cm.

The at least one frame element 2, 2 a, 2 b can be configured identically in the configuration of the seat arrangement 1 with a frame element 2, 2 a, 2 b and in the configuration of the seat arrangement 1 with two frame elements 2, 2 a, 2 b. The at least one frame element 2, 2 a, 2 b is formed by a lower portion 7 and an upper portion 8. The lower portion 7 comprises at least one first transverse portion 9 extending substantially along a width axis Y′, Y and one second transverse portion 10 extending substantially along a width axis Y′, Y. The first and the second transverse portion are preferably formed integrally or in one piece. The first 9 and the second transverse portions 10 can have recesses arranged in a honeycomb-shaped lattice structure (see, for example, FIG. 15). As a result, the lower portion 7 can have a very low weight and nevertheless have sufficient stability. The upper portion 8 further comprises a third transverse portion 11 which extends along the width axis Y, Y′. The two width axes Y, Y′ are congruent in this case. The first transverse portion 9 and the second transverse portion 10 are spaced apart from the third transverse portion 11 along the height axis Z. The first transverse portion 9 and the second transverse portion 10 are connected by means of two strut elements 27. The at least one frame element 2, 2 a, 2 b accordingly comprises an inner surface 28 which is bordered by the upper portion 8 and the lower portion 7, or by the third transverse portion, the two strut elements 27, the first transverse portion 9, and the second transverse portion 10. The at least one frame element 2, 2 a, 2 b is substantially trapezoidal. The third transverse portion 11 has a smaller width than the first 9 and second transverse portion 10. The first transverse portion 9 and the second transverse portion 10 have a greater extent along a depth axis X′ than the third transverse portion 11. The first transverse portion 9 or the second transverse portion 10 form the seat region 4, 4 a, 4 b, at least in portions. The lower portion 7 and the upper portion 8 of the at least one frame element 2, 2 a, 2 b form the at least one frame element 2, 2 a, 2 b integrally, in one piece, or in multiple pieces. FIGS. 4 and 13 each show a one-piece design of the frame element(s) 2, 2 a, 2 b in the region surrounded by dashed lines. These figures also show a further embodiment of the frame element(s) 2, 2 a, 2 b, in which it is/are formed in two parts. For this purpose, the at least one frame element consists of a lower portion 7 and an upper portion 8, in which case both portions 7 and 8 are U-shaped. For this purpose, the two strut elements 27 are advantageously interrupted and connected by means of a detachable connection, preferably a plug connection. Such a releasable connection is, for example, a plug connection. Two portions of the strut element are preferably inserted one into the other. Security devices, such as pins, screws, bolts, etc., are also advantageously provided, by means of which the plug connection can be secured against unintentional loosening.

The at least one frame element 2, 2 a, 2 b can be pivoted relative to the fastening device 5 about a pivot axis 6 extending along a width axis Y. The at least one frame element 2, 2 a, 2 b can be pivoted as a whole with respect to the pivot axis 6. Thus, both the upper region 3 for supporting the back and the integrated seat region 4, 4 a, 4 b are simultaneously pivoted or rotated about the pivot axis 6. In contrast, only the backrest can be pivoted about a pivot axis in conventional seat arrangements. Preferably, the at least one frame element 2, 2 a, 2 b is pivotable into at least two pivoting positions 12 a, 12 b, 12 c, more preferably, the at least one frame element 2, 2 a, 2 b is pivotable into three pivoting positions 12 a, 12 b, 12 c. These pivoting positions 12 a, 12 b 12 c are shown in FIG. 3, for example. In this figure, the double arrow 15 is also shown, which illustrates the pivoting directions again. The at least one frame element 2, 2 a, 2 b is pivotable into a first pivoting position 12 a, in which case at least one frame element 2, 2 a, 2 b extends substantially perpendicular to an imaginary plane 13 which extends parallel to the floor 102 of the means of transport 101 in the first pivoting position 12 a). In other words, the at least one frame element 2, 2 a, 2 b extends upright or substantially parallel to the height axis Z of the seat arrangement 1 in the first pivoting position. In this pivoting position, the seat arrangement 1 has only a minimal space requirement along the depth axis, which substantially corresponds to the extent of the first 9 and second transverse portion 10. The at least one frame element 2, 2 a, 2 b is pivotable into a second pivoting position 12 b, which is inclined relative to the first pivoting position 12 a by an angle of inclination α. Furthermore, the at least one frame element 2, 2 a, 2 b is pivotable into a third pivoting position 12 c, which is inclined relative to the first pivoting position 12 a by an angle of inclination 3. A second imaginary plane 14 can be defined, which runs perpendicular to the first imaginary plane 13. The at least one frame element 2, 2 a, 2 b is substantially arranged in the second imaginary plane 14 in the first pivoting position. In the second 12 b and the third pivoting position 12 c, the at least one frame element 2, 2 a, 2 b each include the angle of inclination α or β with the second imaginary plane 14. The at least one frame element 2, 2 a, 2 b is in this case inclined in directions opposite along a depth axis X in the second pivoting position 12 b and the third pivoting position 12 c. The angles of inclination α and β thus have different signs (±), but the same amount. The angles of inclination α, β are preferably in a range between 10° and 80°, more preferably in a range between 20° and 70°, in which case the at least one frame element 2, 2 a, 2 b and the second imaginary plane 14 include the angles of inclination α, β.

The seat cover 18 is arranged in or above the inner surface 28, which is enclosed by the frame element 2, 2 a, 2 b, or the upper portion 8 and the lower portion 7. If the at least one frame element 2, 2 a, 2 b is made integrally or in one piece, the seat cover 18 can be made designed in a tubular manner. Accordingly, a portion of the tubular seat cover 18 could advantageously be arranged on each side above the inner surface 28. This is shown, for example, in FIGS. 18a and 18b . The tubular seat cover 18 comprises along the height axis Z′ a first upper opening side 48 a, which is preferably closed by means of a seam and abuts the third transverse portion 11. Furthermore, the tubular seat cover 18 comprises a second opening side 48 b, which is lower along the height axis Z′, which is preferably closed by means of an openable closure and lies on top or on the lower portion 7. In the case of a two-piece configuration of the at least one frame element 2, 2 a, 2 b, a flat seat cover 18 can be used. This is indicated in FIGS. 1a to 2b and 5 to 12 d. The edge of the seat cover 18 is connected from the bottom upwards to the at least one frame element 2, 2 a, 2 b. The seat cover 18 is connected to the two strut elements 27 and the third transverse portion 11. For this purpose, for example, a piping rail 65 can be arranged on the inside of the two strut elements 27 and the third transverse portion 11. The piping rail 65 is provided on an inner side of the at least one frame element 2, 2 a, 2 b and thus faces the inner surface 28. This is shown by way of example in FIGS. 1a to 2b . The seat cover 18 has a piping lug 66, which is arranged or clamped in the piping rail 65. Both the flat knitted fabric and the hose-like knitted fabric can have integrated reinforcing fibres which extend biaxially in the seat cover 18.

It is advantageous herein that the seat cover 18 have at least two regions 19, 20 which have different elasticities. A first region 19 has a lower elasticity than the second region 20. The second region 20 is elastically deformable by the action of a force. The first region 19 is arranged along the height axis Z′ above the second region 20. Such a first region 19 can thus be provided and suitable for supporting a shoulder region of the user and is located in the upper region 3 of the at least one frame element or the inner surface 28. The second region 20, which has a higher elasticity, can then be arranged in or above a middle and/or lower portion 28 a of the inner surface 28 along the height axis Z′. Such a second region 20 can be provided and be suitable for supporting the user's lower back and gluteal region. Of course, it would also be conceivable to provide further regions with different elasticities in the seat cover 18. Furthermore, the seat cover 18 is connected to the at least one frame element 2, 2 a, 2 b at the edge from the bottom upwards. By the action of force, the second region 20 forms a three-dimensional deformation 21 or bulge. This is shown schematically in FIG. 3. This force is exerted by the leaning action of the user. Accordingly, when pivoting from the second to the third pivoting position or vice versa, the force is applied in the opposite direction, as a result of which the three-dimensional deformation will also develop in the opposite direction. The seat cover 18 can have a third region 49, which is arranged along the height axis Z′ below the second region. This third region 49 can be connected to the at least one frame element 2, 2 a, 2 b by means of a preferably detachable connection. The third region 49 can be arranged on the first 9 and the second transverse portion 10 and serve as seat upholstery. This is depicted, for example, in FIGS. 18a and 18b . The seat cover 18 can also have an intermediate space or cut-out 50. The third region 49 and the second region 19 are therefore only connected via web-like portions 67 which are arranged on the strut elements 27 of the at least one frame element 2, 2 a, 2 b. This is shown, for example, in FIGS. 18a and 18b . The seat cover 18 cannot have a third region, either. Accordingly, the second region 20 would close off the seat cover 18. The second region can extend up to the first 9 and second cross sections 10 and preferably also be fastened there. The recess 50 can also have an approximately elliptical shape.

The second region 20 accordingly has a preferably curved outer edge 68 (see, for example, FIG. 14. The second region 20 extends in this case as far as a transition portion between the strut elements and the first 9 and second transverse portions 10. Alternatively, the second region 20 merges into the third region 49 without interruption. This is shown by way of example in FIG. 5.

The seat region 4, 4 a, 4 b can be further enlarged if at least one additional element 17 is provided, which is arranged on the lower portion 7 of the at least one frame element 2, 2 a, 2 b. The depth extension of the seat region 4, 4 a, 4 b is increased by the additional element 17. The additional element 17 can be arranged on the upper surfaces of the first and/or second transverse portion or can be arranged adjacent to the upper surfaces of the first and/or second transverse portion. Such an additional element is indicated in FIG. 3 and can be attached to the frame element 2, 2 a, 2 b by a frictional and/or a positive-locking connection. Possible connections are clip connections, screw connections, plug connections, etc. The additional element 17 can also be provided to fix the seat cover 18.

An effective seat surface can thus be defined which comes into contact with the user. The effective seat surface advantageously comprises the first or second seat region 4 a, 4 b and is preferably oriented substantially horizontally, or parallel to the first imaginary plane 13. This effective seat surface is provided by the first 4 a or second seat region 4 b, depending on the pivoting position 12 b, 12 c. The effective seat surface can be provided at least in portions by the upper surface of the first transverse portion 9 or the upper surface of the second transverse portion 10. However, it would also be conceivable that further elements, further layers, covers, upholstery, etc. be arranged on the upper surfaces of the transverse portions 9, 10, which then form the effective seat surface, at least in portions. The additional element 17 can also increase the effective seating surface. The effective seat surface can preferably be formed at least in portions by the additional element 17. However, it would also be conceivable that further layers, covers, upholstery, etc. are arranged on the additional element 17, which then form the effective seat surface at least in portions. An effective seat surface advantageously comprises the first or second seat region 4 a, 4 b of the at least one frame element 2, 2 a, 2 b and a portion of the second region 20 of the seat cover 18. The effective seat surface can also include the third region 49 and, preferably, a transition between the third 49 and the second region 19 of the seat cover 18.

Furthermore, a latching apparatus 29 is provided, by means of which at least one frame element 2, 2 a, 2 b can be locked in at least one pivoting position 12 a, 12 b, 12 c. Preferably, at least one frame element 2, 2 a, 2 b can be locked in the first 12 a, the second 12 b, and the third pivoting position 12 c. It would also be conceivable that the at least one frame element 2, 2 a, 2 b can be locked only in the second 12 b and the third pivoting position 12 c. It is also conceivable that the at least one frame element can assume at least the second and third pivoting positions without the frame element 2, 2 a, 2 b being latched. Due to the inclination of the at least one frame element and an advantageous stop, the frame element remains in this corresponding pivoting position 12 b, 12 c even without any further locking. When the seat arrangement is occupied by the user, the at least one frame element remains in the pivoting position 12 b, 12 c. In the second pivoting position 12 b of the at least one frame element 2, 2 a, 2 b, a first seat region 4, 4 a is formed at least by the first transverse portion 9. This is shown, for example, in FIGS. 1a and 2a . In the third pivoting position 12 c of the at least one frame element 2, 2 a, 2 b, a second seat region 4, 4 b is formed at least by the second transverse portion 10. This is shown, for example, in FIGS. 1b and 2b . In the second pivoting position 12 b of the at least one frame element 2, 2 a, 2 b, the first seat region 4, 4 a extends substantially parallel to the first imaginary plane 13. In the third pivoting position 12 c of the at least one frame element 2, 2 a, 2 b, the second seat region 4, 4 b extends substantially parallel to the first imaginary plane 13. This substantially parallel extension of the first or second seat region 4, 4 a, 4 b allows the occupant to sit comfortably.

FIG. 11a to 11_(d) and 12a to 12d show seat arrangements 1 with two frame elements 2, 2 a, 2 b in different pivoting positions 12 a, 12 b, 12 c. FIGS. 11a to 11d differ from FIGS. 12a to 12d in the design of the fastening device 5. Seat arrangements 1, which comprise a fastening device 5 according to any of the further possible configurations, can however also assume the pivoting positions shown. In FIGS. 11a and 12a , the two frame elements 2, 2 a, 2 b are in the second pivoting position 12 b. Each of the frame elements 2, 2 a, 2 b thus provides the first seat region 4, 4 a in the form of the first transverse portion 9. In FIGS. 11d and 12d , the two frame elements 2, 2 a, 2 b are in the third pivoting position 12 c. Each of the frame elements 2, 2 a, 2 b thus provides the second seat region 4, 4 b in the form of the second transverse portion 10. In FIGS. 11b and 12b , the first frame element 2 a is in the second pivoting position 12 b, as a result of which the first seat region 4, 4 a is provided in the form of the first transverse portion 9. The second frame element 2 b is located in the third pivoting position 12 c, as a result of which the second seat region 4, 4 b is provided in the form of the second transverse portion 10. In FIGS. 11c and 12c , the first frame element 2 a is in the third pivoting position 12 c, as a result of which the second seat region 4, 4 b is provided in the form of the second transverse portion 10. The second frame element 2 b is located in the second pivoting position 12 b, as a result of which the first seat region 4, 4 a is provided in the form of the first transverse portion 9. With such a design, seating groups consisting of such seat arrangements 1 can be flexibly and individually coordinated.

The at least one frame element 2, 2 a, 2 b is arranged on the fastening device 5 by means of a mounting shaft 22. The mounting shaft 22 is received in at least one receiving device 23, 23 a, 23 b of the fastening element 5 in such a way that the mounting shaft 22 is non-rotatably connected to the fastening device 5. Furthermore, the mounting shaft 22 extends through a through channel 24 of the at least one frame element 2, 2 a, 2 b, as a result of which the at least one frame element 2, 2 a, 2 b is arranged to be pivotable relative to the fastening element 5 or the mounting shaft 22. The mounting shaft 22 is shown in detail in FIGS. 4, 13 and 15 to 17 c. The mounting shaft 22 is configured substantially as a hollow cylinder having a substantially circular cross section, for example as a profile tube.

The mounting shaft 22 has at least one, in the present case two, stop elements 30, 31. These stop elements 30, 31 are designed as a recess in the lateral surface 33 of the mounting shaft. The recess preferably extends over the entire extent along the width axis Y of the mounting shaft 22. At least one, in the present case two further stop element(s) 32 a, 32 b is/are arranged in the through channel 24. These two stop elements 32 a, 32 b are configured as a projection on the inner surface 24 a of the through channel 24. The projection preferably extends over the entire extent along the width axis Y of the through channel 24. The through channel 24 can extend along the entire width extension of the at least one frame element 2, 2 a, 2 b or at least along a substantial portion of the width extension. A substantial portion is at least half, preferably at least three quarters of the total width of the frame element 2, 2 a, 2 b. The stop elements 30, 31 of the mounting shaft 22 and the further stop elements 32 a, 32 b of the through channel 24 are each arranged diametrically opposite one another. However, it would also be conceivable for only one stop element 30, 31, 32 a, 32 b to be arranged on the mounting shaft 22 and the through channel 24. The lateral surface 33 of the mounting shaft 20 has two outer regions 34, against which an inner surface 24 a of the through channel 24 abuts in such a way that rotation of the at least one frame element 2, 2 a, 2 b relative to the mounting shaft 22 is made possible. A stop element 30, 31 is provided in the form of a recess between the two outer regions 34 along a circumferential direction 35 of the mounting shaft 22. A radius 36 to the inner surfaces 30 a, 31 a of the stop elements 30, 31 is thus smaller than a radius 37 to the outer regions 34. As can be seen in FIGS. 15 to 17 c, the inner surfaces 30 a, 31 a are designed in such a way that they curve outwards. During a pivoting movement of the at least one frame element 2, 2 a, 2 b, the at least one further stop element 32 a, 32 b of the through channel 24 is displaced along a circumferential direction 35 of the mounting shaft 22 relative to the mounting shaft 22. The further stop elements 32 a, 32 b designed as a projection protrude into the stop elements 30, 31 of the mounting shaft, which stop elements are designed as a recess. The stop elements 30, 31 each have two stop surfaces 30 b, 31 b, 30 c, 31 c, which represent the transition to the adjacent outer regions 34. In the second and third pivoting positions 12 b, 12 c, the further stop elements 32 a, 32 b configured as a projection rest on the diametrically opposite stop surfaces 30 b, 31 b, 30 c, 31 c of the stop elements 30, 31 which are designed as a recess.

Furthermore, a latching apparatus 29 is provided, by means of which the pivoting positions 12 a, 12 b, 12 c, which are possible by the pivoting, can be locked. The latching apparatus 29 is arranged on the at least one frame element 2, 2 a, 2 b, or on the lower portion 7. This is shown by way of example in FIG. 14. The locking device 29 is shown in detail in FIGS. 16 to 17 c. FIG. 17c shows the second pivoting position 12 b. In FIG. 17b , the third pivoting position 12 c is shown. The first pivoting position is shown in FIGS. 16 and 17 a. For reasons of clarity, only a few particularly relevant reference signs are shown in FIGS. 17a to 17c . The latching apparatus 29 comprises a first locking element 42, which can be brought into engagement with at least one further locking element 46 of the mounting shaft 22. A further locking element 46 of the mounting shaft 22 is assigned to each pivoting position 12 a, 12 b, 12 c of the at least one frame element 2, 2 a, 2 b. Furthermore, the latching apparatus 29 comprises an operating element 39, by means of which the first locking element 42 can be displaced. In this case, by displacing the first locking element 42, the engagement with the at least one further locking element 46 of the mounting shaft 22 can be released. Furthermore, the latching apparatus 29 comprises a holding element 38, by means of which the latching apparatus 29 is arranged on the at least one frame element 2, 2 a, 2 b, preferably on a lower side of the at least one frame element 2, 2 a, 2 b, preferably on the lower portion 7 of the at least one frame element 2, 2 a, 2 b along the height direction Z. The holding element 38 is fastened to the frame element 2, 2 a, 2 b by means of a clip connection. However, other connections are also conceivable. The operating element 39 is arranged on the holding element 38, in which case mounting elements 40 are provided between the holding element 38 and the operating element 39. The operating element 39 is pivotably attached to the first locking element 42 by means of a shaft 41 and is thus rockable. The mounting elements 40 are guided in a guide 38 e of the holding element 38. The first locking element 42 is configured like a pin or in the form of a bolt. Furthermore, a reset device 43 in the form of a compression spring element is provided. This is actuated or compressed during the displacement movement to release the engagement. After actuation of the operating element 39, the first locking element 42 can be displaced by the reset device 43, whereby an engagement with the at least one further locking element 46 of the mounting shaft 22 is made possible. The reset device or compression spring 43 is arranged between the locking element 42 and the holding element 38. For this purpose, the first locking element 42 has a radially outwardly projecting collar on which the compression spring rests. The locking element 42 is thus subjected to a spring force which presses the locking element 42 radially inwards. In a non-use state, the locking element 42 engages in a further locking element 46 of the mounting shaft 22 designed as a recess or bore. A plurality of recesses 46 are preferably provided. These recesses 46 are arranged in the outer region 34 of the lateral surface 33 along the circumferential direction of the mounting shaft 22. Three recesses 46 are advantageously provided. The arrangement of the recesses 46 is provided in such a way that, in the predetermined pivoting positions 12 a, 12 b, 12 c, the locking element 42 can engage in a recess 46 which is respectively associated with the pivoting position. The first locking element 42 protrudes through an opening 38 a of the holding element 38, which is surrounded by an outwardly extending raised collar 38 b. The reset device rests on the inside against the raised collar 38 b. Two support portions 39 a, 39 b lie on each of these collars 38 b. The first support portion 39 a is opposite to the second support portion 39 b along a circumferential direction 44. The operating element 39 comprises two operating portions 39 c, 39 d. The first operating portion 39 c is opposite the second operating portion 39 d along a circumferential direction 44. In comparison to the support portions 39 a, 39 b, the operating portions 39 c, 39 d lie farther out along the circumferential direction 44 and along a radial direction 45. When the latching apparatus 29 is operated, one of the operating portions 39 c, 39 d is pressed inwards in the radial direction 45. The respective operating portion 39 c, 39 d can thus be moved into a respective recess region 38 c, 38 d of the holding element 38. Due to the spacing of the operating portions 39 c, 39 d from the support portions 39 a, 39 b and the support of the support portions 39 a, 39 b on the collar 38 b, a lever force acts on the shaft 41, which is arranged centrally on the operating element 39 and connects it to the first locking element 42. The first locking element 42 is accordingly displaced outward in the radial direction 45. This displacement takes place against the spring force of the compression spring 43, whereby the compression spring 43 is compressed. The displacement of the locking element 42 from the respective recess 46 is released, and the at least one frame element 2, 2 a, 2 b can be pivoted.

FIG. 16 shows a non-use position in which the at least one frame element 2, 2 a, 2 b is located in the first pivoting position 12 a. Each further stop element 32 a, 32 b of the through channel 24 is located substantially in the centre along an imaginary circular arc 47 a, 47 b of the first 30 or second stop element 31. This imaginary circular arc 47 a, 47 b extends in each case between the first stop surface 30 b, 31 b and the second stop surface 30 c, 31 c. The first locking element 42 engages into the central recess 46 on the outer region 34 and thus locks this first pivoting position 12 a. In this first pivoting position 12 a, the at least one frame element 2, 2 a, 2 b is generally located substantially perpendicular to the first imaginary plane 13 and is, therefore, in a stowed position. FIG. 17a shows the at least one frame element 2, 2 a, 2 b in the first pivoting position 12 a in two views. In the upper view, the first operating portion 39 c of the operating element 39 has been actuated and thus shifted radially inward into the first recess region 38 c of the holding element 38. In the bottom view, the second operating portion 39 d has been actuated and thus shifted radially inward into the second recess region 38 d of the holding element 38. The engagement of the first locking element 42 from the recess 46 is thus released, and the at least one frame element 2, 2 a, 2 b can be pivoted into the desired pivoting position. In FIG. 17b , the at least one frame element 2, 2 a, 2 b is located in the second pivoting position 12 b. The first further stop element 32 a of the at least one frame element 2, 2 a, 2 b bears against the first stop surface 30 a of the first stop element 30. The second further stop element 32 b of the at least one frame element 2, 2 a, 2 b bears against the second stop surface 31 b of the second stop element 31. The forces applied by the user on the at least one frame element 2, 2 a, 2 b are guided by these stops 30 a, 31 b from the at least one frame element 2, 2 a, 2 b, into the mounting shaft 22, and thus into the fastening element 5. The at least one frame element 2, 2 a, 2 b is locked in this pivoting position 12 b, since the first locking element 42 of the latching apparatus 29 engages in the corresponding recess 46 which is associated with this pivoting position 12 b, on the mounting shaft 22. In FIG. 17c , the at least one frame element 2, 2 a, 2 b is located in the third pivoting position 12 c. The first further stop element 32 a of the at least one frame element 2, 2 a, 2 b bears against the second stop surface 30 b of the first stop element 30. The second further stop element 32 b of the at least one frame element 2, 2 a, 2 b bears against the first stop surface 31 a of the second stop element 31. The forces applied by the user on the at least one frame element 2, 2 a, 2 b are guided by these stops 30 b, 31 a from the at least one frame element 2, 2 a, 2 b into the mounting shaft 22 and thus into the fastening element 5. The at least one frame element 2, 2 a, 2 b is locked in this pivoting position 12 c, since the locking element 42 of the first latching apparatus 29 engages in the corresponding recess 46 which is associated with this pivoting position 12 c, on the mounting shaft 22.

Accordingly, the angles of inclination α, β re predetermined by the length of the imaginary arcs 47 a, 47 b. Furthermore, it is conceivable that the operating element 39 is arranged at a different position of the at least one frame element 2, 2 a, 2 b. The operating element 39 could, for example, also be arranged on the upper portion 8 of the at least one frame element 2, 2 a, 2 b. Furthermore, a gripping element 16 could be provided which is arranged on the upper portion 8. The operating element 39 could be integrated in the gripping element 16. With such a configuration, the mode of operation described in the introduction for actuating the first locking element 42 can be retained. The (lever) force described above, which acts on the axis 41, could be transmitted from the operating element 39 to the axis 41 by means of a transmission device. Such a (mechanical) transmission device could, for example, be a Bowden cable, an actuating rod, or transmission device by means of gear wheels. These transmission devices can preferably be arranged in or on the at least one frame element 2, 2 a, 2 b. However, it would also be conceivable for the transmission device to transmit electrical signals which control an actuator. The actuator then actuates the locking element 42.

On the at least one frame element, at least one gripping element 16 is furthermore arranged on at least one strut element 27 or the upper portion 8. The gripping element is typically arranged on an outer side of the seat arrangement 1, which lies on a walkway of the means of transport. If two walkways are provided, a gripping element 16 can of course also be provided on each outer side of the seat arrangement 1. However, the arrangement of the gripping elements is not limited to the arrangement with respect to the walkways. Such gripping elements 16 can also have other functions, such as support when standing up, etc. It would therefore also be conceivable for at least one gripping element 16 to be arranged on the sides of the frame elements 2, 2 a, 2 b, facing away from the passages.

FIGS. 1a to 2b and 4 show a seat arrangement 1 with only one frame element 2. The fastening device 5 comprises two fastening elements 25 in the form of arm elements 25 a, 25 b, which extend along the height axis Z and open into a base element 26. Starting from the base element 26, the arm elements 25 a, 25 b also extend along the width axis Y, so that they run obliquely upwards. A distance 53 between the first arm element 25 a and the second arm element 25 b decreases downwards along the height axis Z. At an upper end, the arm elements 25, 25 a, 25 b each have the receiving devices 23, 23 a, 23 b for the mounting shaft 22. The receiving devices 23, 23 a, 23 b can be formed integrally, in one piece, or in multiple pieces with the arm element. In a transition region which leads to the receiving devices 23, 23 a, 23 b, the arm elements 25, 25 a, 25 b are advantageously oriented substantially parallel to the height axis Z. The arm elements 25, 25 a, 25 b can be designed as a flat profile. In this flat profile, a preferably circular recess can form the receiving devices 23, 23 a, 23 b. Furthermore, the receiving devices 23, 23 a, 23 b can be designed substantially cylindrical having a preferably circular transverse portion. The base element 26 has a smaller extent along the width axis Y than the mounting shaft 22, or as the distance between the receiving devices 23, 23 a, 23 b. Furthermore, a cover element 51 is provided on the sides of the receiving device 23, 23 a, 23 b. The arm elements can run substantially rectilinear or V-shaped, as shown in FIGS. 1a to 2b and 4. However, an approximately S-shaped course of the arm elements 25, 25 a, 25 b is also conceivable. The base element 26 is either fastened directly to the floor 102 of the means of transport 101, or is displaceably arranged on the floor 102 of the means of transport 101 via a guide device. Such a configuration has the advantage that the base element is arranged centrally under the at least one frame element 2, 2 a, 2 b. A symmetrical introduction of force into the base element 26 can thus take place. This allows the guide system 102 to be designed more simply. If, for example, a rail system is used as the guide system 102, it is sufficient that only one rail be used. In FIGS. 1a and 1b , a fastening element 5 is provided which has a lower height. The base element 26 is merely designed as a cross strut extending along the width axis Y. Such seat arrangements 1 could be used by seniors or children, for example. FIGS. 2a and 2b show a seat arrangement 1 with a seat height for adults. The base element 26 is designed as a substantially rectangular element which comprises two cross struts which extend along the width axis Y. The upper cross strut along the height axis Z is intended as a footrest 52. It would also be conceivable that a rotating apparatus be arranged on or in the base element 26, or be integrated. The fastening device 5, or rather the seat arrangement 1, could then be rotated about a rotation axis 54 which runs parallel to the height axis Z. This is indicated in FIG. 1b, 2b and 3 by the double arrow 55.

The embodiments according to FIGS. 5 to 13 show a seat arrangement 1 with two frame elements 2, 2 a, 2 b, which are arranged on the fastening device 5. The two frame elements 2, 2 a, 2 b are arranged side by side along the width axis Y. As already described, the two frame elements 2, 2 a, 2 b can be pivoted independently of one another about a common pivot axis 6 extending along a width axis Y relative to the fastening device 5 by the angles of inclination α, β into the first, second, and third pivoting positions 12 a, 12 b, 12 c. The fastening device 5 can be designed in different ways. In all embodiments, a mounting shaft 22 is provided which extends along the seat arrangement and extends through the respective through channels 24 of the two frame elements 2, 2 a, 2 b. As already described, such a through channel 24 can extend substantially over the entire width of a frame element 2, 2 a, 2 b. An only partial extension would also be conceivable. A latching apparatus 29 is also provided on each of the two frame elements 2, 2, 2 a, 2 b. The mounting shaft 22 is received in two receiving devices 23, 23 a, 23 b of the fastening device 5. FIG. 13 shows an exploded view of the seat arrangement analogous to FIG. 4. However, only 3 possible configurations of the fastening device 5 are shown in FIG. 13. Of course, the other fastening devices 5 shown could also be inserted in FIG. 13. In these embodiments, at least one cover element 51 can also be provided for closing the mounting shaft 22. The mounting shaft 22 is received in at least two receiving devices 23, 23 a, 23 b of the fastening device 5.

Each of the receiving devices 23, 23 a, 23 b is arranged on a fastening element 25. According to the embodiments according to FIGS. 5 to 11 d, a first receiving device 23 a is arranged between the first frame element 2 a and the second frame element 2 b. Another second receiving device 23 b is arranged on the side of one of the two frame elements 2 a, 2 b, or on one of the two outer sides of the seat arrangement 1. The two receiving devices 23, 23 a, 23 b are substantially cylindrical in shape having a substantially circular transverse portion.

According to the embodiment shown in FIGS. 5 to 6 d, a second receiving device 23 b is arranged on a fastening element 25 in the form of a plate-like first element 56, which can be fastened to a wall element of the means of transport 101. The first plate-like element 56 is accordingly arranged in a fastening plane 58 (see FIG. 6c ) which extends substantially parallel to the second imaginary plane 14. The wall element of the means of transport 101 advantageously includes the fastening plane 58. The first receiving device 23 a is arranged on a fastening element 25 in the form of an arm element 25. This arm element 25 is designed as a cantilever arm or a cantilever. The arm element 25 accordingly extends from the first receiving device 23 a to the fastening plane 58 and ends in a plate-like element 57, which is likewise arranged in the fastening plane 58 and can be arranged on the wall element of the means of transport. Starting from the second plate-like element 57 d, a lower cantilevered portion of the arm element 25 extends obliquely upwards along the height axis Z. The lower cantilevered portion forms an angle with the first imaginary plane 13, which lies in a range between 10° and 45°. An upper portion of the arm element 25 adjoining the lower portion encloses an angle with the first imaginary plane 13, which lies in a range between 45° and 90°. FIG. 5 shows a perspective view of this embodiment. FIG. 6a shows a front view, and FIG. 6b shows a rear view of this embodiment. FIG. 6c shows a side view, and FIG. 6d shows a bottom view of this embodiment. The embodiment according to FIGS. 11a to 11d is analogous to the embodiment according to FIGS. 5 to 6 d. The only difference is that only one plate-like element 59 is provided. This third plate-like element 59 also extends in the fastening plane 58. Furthermore, the second receiving device 23 b is arranged on this third plate-like element 59. Likewise, the arm element 25 opens into the third plate-like element 59.

In the embodiments according to FIGS. 7 to 10 d, two fastening elements in form of arm elements 25, 25 a, 25 b are provided, on which the receiving devices 23, 23 a, 23 b are arranged or integrated. FIG. 7 shows a perspective view of a first embodiment. FIG. 8a shows a front view, and FIG. 8b shows a rear view of this first embodiment. FIG. 8c shows a side view, and FIG. 8d shows a bottom view of this first embodiment. FIG. 9 shows a perspective view of a second embodiment. FIG. 10a shows a front view, and FIG. 10b shows a rear view of this second embodiment. FIG. 10c shows a side view, and FIG. 10d shows a bottom view of this second embodiment. In these embodiments according to FIGS. 7 to 10 d, both arm elements 25, 25 a, 25 b are designed as flat profiles and can be fixed on the floor of the means of transport 101. For this purpose, a fastening region 60 is formed on the respective arm element 25, 25 a, 25 b, which has a portion parallel to the floor of the means of transport. Bores can be provided in this portion, by means of which the fastening is made possible, for example, by a screw connection. The two arm elements 25, 25 a, 25 b are inclined with respect to a reference axis 61, which runs perpendicular to the first imaginary plane 13. An angle of inclination γ can thus be defined between this reference axis 61 and a central axis 62 of the arm elements 25, 25 a, 25 b. This is shown by way of example in FIGS. 8a and 9a . The angle of inclination γ lies in a range between 5° and 20°, preferably in a range between 10° and 15°. The second receiving device 23 b and the second arm element 25 b connected to it are advantageously provided on an outside of the seat arrangement 1, on which a gripping element 16 is also provided on the corresponding frame element 2, 2 a, 2 b. As a result, the forces introduced into the seat arrangement 1 by the one gripping element 16 can be effectively derived via the second arm element 25 a. The seat arrangement 1 accordingly has an advantageously increased stability on the outside of the seat arrangement 1. As in all of the embodiments presented, the arm elements 25, 25 a, 25 b and the associated receiving devices 23, 23 a, 23 b can be designed integrally, in one piece or in multiple pieces. Likewise, the through channels 24 can extend substantially over the entire width of the frame element 2, 2 a, 2 b or only in portions. In FIG. 8d it can be seen, for example, that the passage channel 24 only extends in portions along the width direction Y′. The two receiving devices 23, 23 a, 23 b in this case comprise an extension element 63 which extends along the width direction Y′ of the frame elements 2, 2 a, 2 b. The receiving devices 23, 23 a, 23 b and the corresponding extension element 63 can be formed integrally, in one piece, or in multiple pieces. The extension element associated with the first receiving device 23 a extends from the intermediate space between the frame elements 2, 2 a, 2 b along the second frame element 2 b. The extension element associated with the first receiving device 23 a extends from the outer side to the intermediate space between the frame elements 2, 2 a, 2 b along the first frame element 2 a. In contrast, the through channel 24 according to the embodiment according to FIG. 10d extends over a substantial portion of the width direction of the frame elements 2, 2 a, 2 b. A substantial portion is to be understood as meaning at least half, preferably three quarters, of the total width of the frame element 2, 2 a, 2 b. In the embodiment according to FIGS. 7 to 8 d, a footrest 52 or a footrest element is provided on each arm element 25, 25 a, 25 b. Starting from the respective arm element 25, 25 a, 25 b, this footrest 52 extends substantially parallel to the first imaginary plane 13 or the floor of the means of transport.

According to an embodiment according to FIGS. 12a to 12d , the first receiving devices 23, 23 a and the second receiving devices 23, 23 a, 23 b of the fastening device 5 are arranged on the outer sides of the seat arrangement 1. The two frame elements 2, 2 a, 2 b are thus arranged between the receiving devices 23, 23 a, 23 b. Only a preferably sleeve-shaped spacer element 64 is provided between the two frame elements 2, 2 a, 2 b. This fastening device 5 is designed analogously to the fastening device according to FIGS. 2a and 2b . The corresponding description is therefore analogous. The two S-shaped or V-shaped fastening element 25 in the form of arm elements 25 a, 25 b likewise open into a base element 26. An advantageous symmetrical introduction of force into the base element 26 can thus also take place. Analogously, a rotating device can also be provided, by means of which the seat arrangement 1 can be rotated about a rotation axis 54.

An interior device 100 for a means of transport 101 is shown in FIG. 19. This interior device 100 comprises a plurality of seat arrangements 1. These seat arrangements 1 are firmly fixed to the floor of the means of transport 101 or are guided in a guide system (not shown). This guide system can be, for example, a rail device and is preferably arranged on the floor of the means of transport 101. Alternatively, a guide system could be provided on a wall element of the means of transport 101. A specific number of seat arrangements 1 could thus initially be stored in a stowage region 103 of the means of transport 101. Depending on requirements, the required number of seat arrangements 1 can be distributed from the stowage region 103 along the guide system 102 in the interior of the means of transport 101. This can be done manually or by an actuator. These seating options should be able to be modified to meet different needs. Such needs are, for example, the adjustment of the seat orientation with respect to the direction of travel or the adjustment of facing seating groups. If baggage or bulky baggage is present, fewer seat arrangements 1 can accordingly be removed from the stowage region. Such an interior device 100 having the seat arrangements 1 can provide more than 25% more seats than the previous seat arrangement. In the first pivoting position 12 a, i.e., the upright orientation, the seat arrangements 1 along the depth axis X only assume the depth of the seat portion 4 of the frame element 2, 2 a, 2 b. The seat arrangements 1 can therefore be stored in an extremely space-saving manner. Also in the second and third pivoting positions 12 b, 12 c, the seat arrangements 1 have a considerably smaller space requirement in a depth direction X. The space requirement in the depth direction is determined by the angle of inclination α, β and the foot space required. The user assumes a sitting posture in the seat arrangement 1, which approximately corresponds to a standing posture. This sitting posture, however, has a considerably lower space requirement than the conventional sitting posture, in which the legs are angled at approximately right angles. The seat arrangements 1 advantageously allow an extremely comfortable adjustment of the seat orientation due to their pivotability. This means that seating groups can also be easily modified. This is shown by way of example in FIG. 19. The seat arrangements 1 each have two frame elements 2, 2 a, 2 b. A first seating group 104 is a group of four. The two frame elements 2, 2 a, 2 b of two successive seat arrangements 1 are inclined in such a way that two users face each other. A second seating group 105 is a group of three. Here, a frame element 2 a is oriented such that the user faces a seat arrangement with two frame elements 2 a, 2 b. The remaining frame element 2 b is used as a single space 106. In a third seating group 107, the seat arrangement 1 is used as a two-seater. In this case, both frame elements 2 a, 2 b are inclined or aligned in the same direction.
